Automotive OEMs can improve the safety of their lithium-ion battery packs with robust communications, comprehensive diagnostics, and lower system costs with the MAX17843 12-channel, high-voltage smart sensor data-acquisition device from Maxim Integrated Products.

EVs, hybrid EVs, and plug-in hybrids rely on big lithium-ion battery packs containing hundreds or thousands of individual cells. Industry experts are predicting that 25% of cars sold by 2025 will have an electric engine. Therefore, automotive OEMs and Tier 1s need an intelligent battery management system to offer safe, low-cost solutions with robust communications.

The MAX17843 meets the highest safety standards, adhering to ISO 26262 and ASIL D requirements (also applicable for ASIL C). Its differential UART using capacitive isolation reduces BOM costs and failure in time rates. With this, designers can save up to 90% of their isolation BOM cost.
